sink waste into soil pipe??

[AndyBill]

Hi,
as im about to start to think about starting the en-suite shower/toilet/sink i was wondering if it is possible to put the sink and shower waste pipes directly into the 150mm horizontal soil pipe within the area of the en-suite.
Is that allowed and ok? or do i have to run all the 3 waste pipes across the bedroom and out through the wall into the vertical soil pipe?


cheers for any advice

Andy

That should be your sub stack.

Can you describe it
